Application filed June '14,

upwardly extending openings in the central or bottom part thereof for directing steam 15 from the vessel around the chemical-retaining pocket and into the interior of the bowl.

Other-objects of the invention and the various advantages and characteristics of the present vaporizer construction, will be ap- 23 parent from a consideration of the following detailed description.

The invention consists in the several novel features which are hereinafter set forth and ,are more'particularly described by claims at 25 the conclusion hereof.

p In the drawings which accompany and form a part of this specification or disclosure and in which like numerals of refer- V ence denote corresponding parts throughout the views; Fig. 1 is a vertical section of a vaporizing device embodying the invention.

Fig. 2 is a plan View.

The vaporizing device which forms the subject matter of the invention comprises a bowl 5 of sheet metal. The bowl is concavo convex in conformation, and is adapted to rest on an ordinary vessel, such as a cup 6 containinghot. water; The'bottom of the bowl is depressed to form a downwardly extending pocket 10. Thelatter serves to retain a chemical 8 which is adapted to be vaporized by heat and may be in liquid, powder, or crystal form. The bowl is extended outwardly beyond the rim of the cup 6, and

i has formed therein between the rim-engaging portion and pocketlO a series of openings 9. The upper end of the bowl is open for the escape of the vapor. By forming the pocket 10 in the lower portion of the bowl, it will extend into the cup sufficiently 1929. Serial m. 370,867.

to' be submerged in the hot water in the cup 6,so it will be heated thereby. Thesteam from the 'water' in the cup willrise through the openings9 and pass upwardly into the bowl and be'mixed with. the vapor produced by the heated'chemical. I i In using the device, the pocket 10 is first filled with'the desired chemical and then the bowl is placedupon the rim. of thefcup. Thereafter, the user holdshis "or her head over the bowl 5 and inhales the vapor emanatingfrom and around .the pocket; The vaporizing device herein'disclosed is exceedingly simple as far as construction I 'is concerned and is'capable of being set on vessels that vary in diameter by virtue of the fact that it comprises a bowl. Inasmuch as the bowl and pocket are made from a single piece of sheetmetal, the cost of producing the device is reduced to a minimum. A characteristic and an advantage of utilizing a concavo convex bowl is-that the rim of the cup is effectively sealed against leakage of steam.

The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention. I

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is:

1. A vaporizlng device of the character described, comprising a member adapted to set on the top of an ordinary vessel containing hot water, and provided at the central portion thereof with a depending pocket for holding a chemical, the margin of the member being extended and adapted to. rest loosely on the rim of the vessel, the portion of the member between the margin and the pocket having holes formed therein for di- 'recting steam from the vessel. upwardly through the member and around'the pocket.

2. vaporizing device of the character-v described, comprising a bowl adapted to set on the top of an ordinary vessel containing hot water, and provided at the central or bottom portion thereof with a depending pocket for holding a chemical, the margin of the bowl being adapted to rest loosely on the rim of the vessel and extending outwardly and upwardly from the rim-engaging part to form an enlarged chamber with an open top, the portion of the bowl be- 5 tween said rim-engaging part and the pocket being substantially flat and having ,a plurality of holes j formed therein ffor directing steam'from the vessel upwardly around the pocket and into the chamber. W 3. A vaporizing device of"the eharacter described, comprising a one-piece sheet metal bowl adapted to set on the top of an ordinary vessel containing hot water, and

having an integral depending chemica'hhol'ding pocke pres i t e c ntr l, o b tom f rt on thereof, ,themargin of the member g gred p ed to rest o sely o t e m O we ve e e t nd u w rd y n pwardly from the-rim-engaging-part to form an enlarged chamber with an open top, the

portion of the bowl between said rim-engagmg part and the pocketbeing substantially fiat and havinga plurality ofholes formed .thereinfor directing, steam from the vessel upwardly around the pocket and into the Chamber.
